Re JonePeng:
This is executed one after another, not "simultaneously"; but I guess the "simultaneously" the original poster mentioned is this kind of simultaneous. To achieve approximate simultaneous execution, you must call programs in a multitasking environment. Therefore, in a pure DOS environment (meaning without loading any extension programs), it is impossible to achieve.
And under Windows, you can use start to call batch files to achieve polling-style "simultaneous" execution. I did some tests under XP, which is very interesting. Anyone who is interested can also test it and discuss the reason.
After downloading the attachment test.rar and extracting it, execute sp.bat in it, and then observe the execution result.

Remove the pause>nul inside. It's like this again.
D:\MultiTaskTest>sp.bat
5
D:\MultiTaskTest>start 1...
end 1.
start 2...
D:\MultiTaskTest>end 2.
D:\MultiTaskTest>start 3...
end 3.
start 4...
D:\MultiTaskTest>end 4.
D:\MultiTaskTest>
It seems that without removing pause>nul, batches 1-4 seem to execute simultaneously again.
D:\MultiTaskTest>sp.bat
5
D:\MultiTaskTest>start 1...
end 1.
start 2...
D:\MultiTaskTest>end 2.
D:\MultiTaskTest>start 3...
end 3.
start 4...
D:\MultiTaskTest>end 4.
D:\MultiTaskTest>

Realize polling-style "simultaneous" execution??

Of course, it's easy under WINDOWS. If it's under DOS, it's also feasible. But this requires using TSR technology.

It seems that without removing pause>nul, batch processing 1-4 seem to execute simultaneously again.
